I 'it h these and incidental objects in view, the invention consists incertain novel features of construction and combinations of parts. theessential, elements of which are I se t foi-s nappended claims and apreferred foi i of embodiment of which is hereinafter specificallydescribed with reference" to." the drawings which accompany and formpart of this specification.

f the drawings, Figure 1 is-a transverse vertical section taken throughamachine having the present invention applied thereto and showing thekey controlled differential mechanism and the operating mechanism intheir normal positions and the indicator in its zero position. Fig. 2 isthe same as Fig. l butshows the indicator in zero position with thealining pawl fontl ef'indi'cator out of engagement therewith and thiejkey controlled differential niechanisniis shown in disconnected from theoperating mechanism the position in which it is after ithas been by thedepressed nine key. Fig. 3 is 'same asFig. 1 and shows the keycontrolled differential mechanism in-the position shown in Fig. 2 withthe indicator in its nine posi tion and the alining pawl in lockingposition.

Fig. 4 is a detail of the differential mecha ,nism, indicator and partof the operating 'ni'eclianism shown in Fig. l and shows thekeycontrolled differential mechanism and operating mechanism" in normalposition,

and the indicator in its nine position. I 5 is afront elevation-of Fig.1 with the key board and the operating cams removed. Fig. 6 is a, detailof a cam and an armfor operating the alining pawls for the indicator.

Described in detail and with reference to the drawings the illustrativeregister with I the improvements embodied consists of a I plurality ofbanks or sections and each bank forms a unit and the number of banksdepends upon the registering capacity desired.

, One of these sections is shown in the figures and but one section willbe described, it bevided for each bank or section of the ma chine. Athree armed lever 3 journaled on a stub shaft 4 in a frame 5, which iscarried by rod 6, and shafts 7 and 12 carries at its lower'armsoppositely extending. rollers 8. There is one of these. plates or frames5 for each bank or section of the machine and each frame supportsvarious parts of the machine for its bank or section, as will bedescribed.

Eachof the rollers S- rides on the face of one of the pair of cams 2'provided for that particular bank. The shape and arrange- .ment of apair of these cams '2 is such that.

on'every rotation of the shaft 1 the lever 3" will be rocked firstclockwise retained in this position for approximately one-half rotawillalso be rocked about its pivot 9 and as the link connects the plate 10and the lever 3 above their respective centers, the plate always rockswith the leverfirst clockwise and then counterclockw1se. Loosely mountedontlie screw 9 and adjacent the platelO is an arm 13. The enlargedportion ll of the arm 13 is in the form of a sector with its teeth'15 infixed engagement with the teeth :of a segment gear 16 which is pivotedat 17 to the frame Attached to the forward 'end of the arm '13 by thepivots 19 is a link 20 and a bell crank lever 21. This link and the bellcrank lever carry on pivots 22 a latch 23 which is at all times drawnrearward by a spring 21 so that the rear end of the latch 23 is normallyheld in engagement with a cut 25 in the plate 10, establishing anoperative connect-ion between the plate 10 and the arm 13 so that thetwo will move together as long as the latch 23 remains in engagementwith the cut. 25 in the plate. Unless a key in the bank isdepressed thehitch is withdrawn from the cut inthe plate 10 at the very beginning ofthe operation of the machine by a pawl 27 which is pivotcdat 28 to thelowerendof a'pla te 29, and at all times urged by a spring (not shown)into the position shown in Fig. 1, with its nose 3O resting in the pathof a block 31 rigidly secured to the forward end of the bell crank lever21. hen the plate 10 is rocked clockwise by an operation of the drivingmechanism the arm 13'and the parts pivotedIthereto. will, owing to thefact that the latch isat the time seated in the cut 25, also start tomove clockwise. However, the nose '30 on the pawl 27 acting against theblock 51 attached to the bell crank 21 will rock the be l crank and thelink 20' on their pivots 19 drawing the latch 23 out of engagement withins ' Lung-386 'the "out and projecting the forward end 33 of the latchinto the lowest one ofthe notchesBl in the plate '29'secured to the keyframe. This stops further upward movement of the arm 13 and latch 23,and downward movement ofthese :parts because of gravitation 'ispreventedby the rear end of the latch23 ridingon theperiphery 36 of the-plate 10.After the latch??? is.discon-= nected from. theplate 10 the lattercontinues to theend of its clockwise movement independent of th'e'plate13 and then later swings back. toward normal, position; When, duringthis return movement, the cut 25-.in the plate 10 is brought oppositethe rear end of the latch 23 the spring'2 draws the latch intoengagement with the cut 25'and the arm 13 and its attached parts arereturned tobecome ii'ieifective through any cause. accompl' i thisresult the portion 37 of the plate ll'Ojabove'the cut pro ects beyondthe periphery 36 of the plate below the cut so that as the plate 10returns to its starting point this extending portion 37 will engage therear end of the latch 23 and draw 1t I as soon as this downwand movementof h latch begins the latch is cammed rearward into the cut25 and theparts involved are all carried by the completion of the operation to thepositions they occupied before the operation was begun.

The. lowest notch 34: in theplate '29 and into which the latch 23 wasprojected when no amountkeyis depressed, as just described, is a zeronotch. The notchnext above it is the one that the latch engages when oneisrt o be registeredand so on up to the top notch, whichis the oneengaged by the latch 23 when nine is to. be registered. lVhen anamount'is tobe registered the position takenliy the latch is determined by thekeys 38. 'These keys are mounted radially to thestub shaft 9 in a frame39 supported by. cross bars LO evtendmg through the machine; Lateralmovement of the keys is'. prevented by guide plates .43 secured to theframe'39, and so arranged that the-ke s are. free to move end-wise anextent in one direction determined by the heads of the kevs and int-heother direction by the shoulder.il ofsthe keys engaging the under sideof the plate all forming. part of the frame 39. In the accompany-nundrawings the devices for: latching the keys in then."

depressed position until they .have served their purpose, mechanism forreleasing the kcv'latches and theusual springs for returning the keys tonormal position have depended upon to cut 25, additional manners onebeen left out. These features are omitted,

however, only to make the drawings more eas ly read and it is to beunderstood that the machine is provided with these means.

Ad acent the bank ofk eys'is aplate 45 swung from a link 46 and a pawle7 pivotally attachedat {1:8 and-l9} respectivelyto thekey frame 39.Pins 50 on this plate extend laterally under the keys 38. The pawl 4C7has a finger 52 which engages a stud 53'on the pawl 27. When any one ofthe keys 38 is pressedinthe cam surface on its lower edge will actagainst the op posed pin 50 and force the plate at?) down therebyswinging the arm 46 and the pawl 47 about their pivotsland causing thefinger 52 of the latter acting against the stud 53 on the pawl 27 todraw the pawl 27 back so that its nose 30 will be carried out of thepath of the block 31 attached to the bell crank 21. The key is thenretained in depressed position. partly by the pin 50 engaging the notchon the lower edge of the key but mainly by the latching devicesmentioned above but which are not shown in the drawings. As shown inFigs. 2 and 3 the depth of the notch is such that when the key isretained in its fully depressed position-the plate 45 is locked down'and the nose 30 of the pawl 27 is heldback out of the path of the block31 secured to the bell crank :21. This permits the arm l3 to be carriedup by the plate 10 until the block 31 strikes the inwardly projectingend of the depressed key when the latch is disengaged from 'the cut 25in the plate 10 and projected into the notch 31h corresponding to thekey depressed. On the return of the plate 10 the planners in the plate=10 areengaged and the parts returned to normal position as describedabove in connectionwith the operation of the machine when no key in thebank was depressed. As soon asthe plate 10 and the arm 13 reach theirnormal positions theplate i5 is "depressed by key releasing devices (notshown but men tioned above) and the key is restored by its spring (notshown) permitting; a spring (not shown) to restore the pawl 27 and theplate 45 to the position shown in Fig". 1.

T he segment gear 16 is DlVOthllV connected at 57 to one end of a link58 which at its opposite end isconnected at 5 to a segment real-'60. Thesehn ent {lea-r meshes engagesv the teeth of the pinion (S1 to lock-:the. indicator against movement.

Near one end of the shaft 67-. (Fig. 1) is a down- Wardly projecting arm70 which at its lower Fast to-a shaft 67 extending lonend carries pin 71pass ing through slot :72-formed inth'ejupper end of an'arm 73 "which isloosely; mounted on the-shaft 7 Loosely mounted 'inlt e shaft"? butrigid arm '74, (Fig and. the arm 74 at itsfree end carries a roller 75which plays in a cam groove 76 formed on the face of a disk77 which isfast to the main drive shaft 1. This cam through the engagement with the'be used throughout above described connections is adapted to rock thealinin-g pawl '68 out of and into pinion 61 at the proper times. I I

The plate 64- is loosely secured by'the screw 78 to the upper. end of anarm 79 extending vertically upward from the outer periphery of aring-shaped 'member 80.

' This arm -79 together with the ring-shaped portion 80 comprises whatwas referred to in the general description of themachine as a floatingmember and that-term will also the specification. The inner periphery ofthe ring-shaped portion 80 of the floating member is concentric with theouter periphery of the member. The periphery of a. circular disk 81shown in dotted lines in Figs. 1, 2 and 3, is greater than the innerperiphery of'the ring-shaped portion 80'of the floating member, but'lessthan the outer periphery of this portion of the floating member: and thedisk carries three pins which project from the right 'hand side face ofthe disk and are arranged equidistant from each other, so that theanti-friction rollers with which the pins are equipped ride freely onthe inner periphery of the ring-shapedportion 80 of the floating member.The pins 83 are provided with heads 84: to hold the disk in place on themember, there being-sufficient space between the disk and the heads ofthe-pins-to permit rotary movement of the disk Without undue a lever 89(Figs. 1 to and the lever is mounted just to the left of tl1e' 'd is k81.

The alining pawlGS is then rocked back tonormal locking engagement with the indicator pinion 01 by its camTli-and the lever '89. through the intermesliing gear 93 and segl'nent'gear 94, is turned back to normal position without afl'ejcting theposition ofth floating member as the shaft- 12 is now at the pivotal aswell as the geometrical center of the disk 81 and the turningot'thelever Sil'merely results ina similar turning of the disk.

During approximately the-last 'one-quarter rotationot' the main driveshaft 1 and after the lever 89 is restored to normal position the plate10 and the difi'erential arm 13 are also restored. to their normalposition and.

the segment gear 10 is in its turn turned clockwise to normal position.As the indicator 62 I is again locked against rotation upon the returnmovementot' the segment gear 16'to normal position the indicator settingsegment gear 00 is forced to roll about the pinion 61 and the pivot 63for the segment gear '00 is carriedrearward thereby raising the floatingmember and the disk 81. The position of'the parts of the machine afterthe operation ust described has been performed is shown in Fig. 1 inwhich position they remain until at the beginning of the next operationof the machine. v

As Fig. -i shows the differential arm 13 in its home or normal positionand the indi cator 'in its nine position this position beindlcated bythenumeral "9 on the Hulk 'cator. the reverse of the operation ustdescribed, that is movement of the indicator from its nine to its zeroposition. will be taken to illustrate the operation of the ma;

chine when the indicator is moved from a higher to a lower indicatingposition. v In this case no amount key 38 is depressed and the zero pawl27 operates-the latch 23 to dis connectthe differential arm 13 from theplate 10 so that movement of the plate 10 is effected unaccompanied bythe arm 13. After the plate has been given its full ex.- tent of upwardmovement the alining pawl 08 is rocked out of engagement with the pinion01 rigid with the indicator and the lever 89 is then given itsone-quarter rotation in a clockwise direction. The radius of the lowerportion of the slot '85 is less than the radius for the upper portion ofthe slot. This difference in the curvatiire of the upper and lowerportions of the slot is provided as the stud 91 carried by the leverSQ-is normally below the shaft 1:? and when the floating member israised so that the shaft 12 is below the geometrical center of'the disk81 (Fig. 4) the stud 91 is nearer the periphery of the disk than is theshaft 12, whereas when the floating member is loweredthe same extentabove the geometrical center of the disk. the shaft is nearer theperiphery of the disk than the studybut it is .then thethat after therearwardly extending arm of the center of the disk than is the shaftBQof the slot relative to the stud 01 and shaft same distanceirom theperiphery as it is when the floating member is raised. If the lowerportion of the slot 85 was of the same radius as the upper portion itcan be seen the lever 89 p cks up the stud 102 and then tends to movethe floatin member toward the-front of-tlie machine t lat the slot wouldnot be constructed to permit the disk'Sl to move freely in lateraldirection and at the same time in a rotary direction, the 11 )perportion of the slot being constructed to allow simultaneousmovement whenthe disk is elevated because the stud 91 is then nearer so But as theradius of the lower portion of the slot is less than the u per portionand as the stud is nearer the ower end of the slot the floating memberwould be drawn down past the position shown in Figs. 1 and 3 before therearwardlv extending arm 'of the lever 89 engaged the stud 10'. and thenit would be moved upto this constant position if it were not for thefact that the position 86 gradually changes before the arm of the lever89 engages the stud 102. The curvature of the lowerportion of the slotis con-,- structed topermit the bodily movement of the disk 81 downwardand to the rear of the machine during its rotary movement so that thepivotal center of the disk is gradually changing. Then when the lever 89engages the stud 102 the floating member and the. disk 81 are movedstill farther downward and toward the-rear to normal position and thismovement given by the engagement of the lever with the stud 102. becauseof the shape of the slot 85. pulls the floating mem-, ber downward itslast increment of move- 105 ment to its constant position shown in Figs.1 and 3. The plate 10 is then restored to normal position and uponreaching Zero position the latch 23 1S pulled rearward to couple the arm13 again with the plate. \Vhen the floating member and disk 81 were sopulled'ilownw'ard to their constant position the alining pawl 08 was'out of locking en 'gagement with the pinion 01 so that the segment gear60 was forced to rock counterclockwise to move the indicator from itsnine to its zero position.
